Standard Ignition Distributor Vacuum Advance P/N:VC-242
Keep your distributor advancing spark timing on schedule with the Standard Ignition Distributor Vacuum Advance VC-188. This vacuum advance unit uses engine vacuum to advance ignition timing as load and throttle change, helping the distributor deliver the correct spark timing across the operating range. It's a direct-fit replacement for a wide list of 1970s Chrysler, Dodge, and Plymouth vehicles — including the 1975-1976 Chrysler Cordoba, 1974-1978 Chrysler New Yorker, 1974-1976 Dodge Charger, 1974-1978 Dodge Ramcharger, 1974-1978 Plymouth Fury, and many more (see the Buyer's Guide tab for the full list).
Signs the original may need replacing include a diaphragm that won't hold vacuum, a leaking or seized advance, or timing that no longer advances with vacuum. If a failed vacuum advance is the cause, this unit replaces it.
